Cooperative transmission scheme of relay selection combined with network coding and its performance analysis
The outage probability and average BER (bit error ratio) of two-way relay system with network coding using relay selection were analyzed over Nakagami channels. The cooperative relay selection criterion of minimizing the worse user's BER was proposed based on three time slots network coding. Th...

| description | The outage probability and average BER (bit error ratio) of two-way relay system with network coding using relay selection were analyzed over Nakagami channels. The cooperative relay selection criterion of minimizing the worse user's BER was proposed based on three time slots network coding. The closed-form expressions of outage probability and average BER were derived through theoretical analysis from the point of two-way communication; meanwhile, the analytical expressions of outage probability and average BER of two-way relay system using network coding without cooperative relay selection were also obtained rigorously. By the analysis of two-way relay system without cooperative relay selection, it was found that the performance gains of the proposed scheme would increase gradually with the Naka-gami channel fading parameters decreasing. Simulation results verified the correctness of theoretical analysis and illus-trated that the performance of the proposed scheme can be improved significantly relative to the network coding without cooperative relay selection. |
